    =========================================================
 
+* mbuf: The control mbuf API has been removed in v18.05. The impacted
+  functions and macros are:
+
+  - ``rte_ctrlmbuf_init()``
+  - ``rte_ctrlmbuf_alloc()``
+  - ``rte_ctrlmbuf_free()``
+  - ``rte_ctrlmbuf_data()``
+  - ``rte_ctrlmbuf_len()``
+  - ``rte_is_ctrlmbuf()``
+  - ``CTRL_MBUF_FLAG``
+
+  The packet mbuf API should be used as a replacement.
+
+* meter: updated to accommodate configuration profiles.
+
+  The meter API is changed to support meter configuration profiles. The
+  configuration profile represents the set of configuration parameters
+  for a given meter object, such as the rates and sizes for the token
+  buckets. These configuration parameters were previously the part of meter
+  object internal data strcuture. The separation of the configuration
+  parameters from meter object data structure results in reducing its
+  memory footprint which helps in better cache utilization when large number
+  of meter objects are used.
